"You're already hosting the Premier League, and we believe we're the premier sport in the world," Kraft said, according to ESPNBoston.com. "I think London has shown, with the way they've handled the Olympics and every other major sporting event, that it's time for you to have your own NFL franchise, based in London."

Sunday's Rams-Patriots game is the sixth regular-season game played in London, a series that started in 2007 and has continued on a yearly basis.

"As these things develop and there's a permanent home team now, I'm sure they'll develop a great following," Kraft said. "Whatever we can do to cultivate playing football throughout the world. ... I don’t know if we've done as good a job as we could educating the rest of the world on what a great game it is.”
